UPIIOLSTERING-MACHINE.

Specification of Letters Patent.

Patented June 14, 1921.

Application filed May 5, 1919. Serial No. 294,651.

To all whom it may concern Be it known that I, EMIL J. Lone, citizen ofthe United States, residing at San Francisco, in the county of SanFrancisco,

5 State of California, have invented a new and usefulUpholstering-Machine, of which the following is a specification in suchfull and clear terms as will enable those skilled in the art toconstruct and use the same.

10" This invention relates to a cushion stufiing machine and its objectis to provide a machine whereby the hair, cotton or other material usedfor stufiing cushions may be placed therein in the proper positionwithout wadding it into lumps, and also whereby a set of springs may beincluded within the cushion at the same time.

It will be understood by those skilled in the art that in producingcotton, hair or fiber filled cushions that it is very necessary to havethe filling evenly and smoothly disposed within the cushion cover if therushion is to be nicely shaped. In the present instance, this machine isfor the purpose of permitting the assembling of the cushion materials ina heap slightly larger than the cushion itself, after which thematerials are compressed into the machine sufficiently for the cushioncover to be placed thereover, whereupon the machine is withdrawn fromthe cushion, leaving the hair, cotton or fiber within the cushion coverand expanded against the same, and enough to produce a smooth, firmcushion.

A further object of the invention is to provide a machine which will becapable of stuffing seats, cushions, mattresses or other similarupholstered objects with, the requisite amount of fibrous material,springs, or of hair, cotton or other suitable fiber.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the drawings in which thesame reference numeral is applied to the same portion throughout, but Iam aware that there may be modifications thereof.

In the drawings:

Figure 1 is a side elevation of the com plete machine,

"Fi 2 is an end view of the complete machine looking from the left Fig.1,

either Fig. 3 is a plan view of the complete machine, and

Fig. 4; is a longitudinal sectional view of the machine.

The machine comprises a base 1 which is supported by four suitably heavytubular posts 2, 8, 41, and 5, the posts having fioor flanges 6, andtransverse tubes 7 for making the structure more rigid.

The base is also connected withthe posts by means of suitable flanges 8.

Above the base 1 and connected theretoby means of suitable fioor flanges9 are four posts 10 to 13 inclusive, said posts being connected withpipe fittings known as Ts 15 to 18 inclusive. Pipes 19 and 20 areslidable in the Ts 16, 17, and 15, 18 respectively, and these two pipesare in turn connected to a cross bar 21. The bar 21 has the threaded bar26 screwed thereinto with sufficient pressure to prevent it fromrotating during the operation of the clutch member 29.

The base 1 is provided with a subsidiary base 23 which has two postscarrying guides 24, 25, through which the screw 26 may slide. The guide24: supports a tubular slide 28, while the guide 25 supports a tubularslide 27.

Threaded on the screw 26 there is a clutch member 29, and it is mountedbetween the ends of the two tubular guides 27, 28 so that it cannot movelongitudinally with respect to the screw 26 unless it is rotated.

Loosely mounted upon the two tubular slides 27, 28 are two outer clutchmembers 30, 31, springs 32, 33 being used to hold the clutch members 30,31 normally disengaged from the clutch member 29, with which either maybe engaged when required, as will be later explained. The machine isdriven by belt 70 and the cross belt 71 passing around the outside ofthe clutch members 30 and 31.

The angle of face of the clutch members 30, 31 and the opposite faces ofthe clutch member 29 is such that the clutch members 30 or 31 areengaged with the clutch member 29 that they will remain so engaged untila suitable force is applied thereto to disengage them. The object ofthis is to produce an apparatus which will automatically disengage thedriving power from the threaded nut clutch member 29 as soon as the beam21 reaches either end of its throw.

Each of the clutch members has a boss against which bear thrust collars34, 35 which boss is moved longitudinally with respect to the screw 26by means of the levers 36, 37. The levers 36, 37 are mounted under theguides 24, and below the screw 26, and they are operated to throw eitherof the clutch members into engagement with the clutch member 29 atthewill of the operator by means of the levers 38, 39. These twoleversarein turn operated by pedals 40, 41 connected with rods 42 and 43. Thefoot pedalse40, 41 are pivotally mounted on a floor bracket 44 below thecushionmaking hopper and in convenient reach for the feet ofthe-operator. The levers 38 and 39 are so shaped that when either of thelevers 38 or 39 are moved they will cause the engage ment of one or theother sides of the clutrh members 30,31, andwhen so engagech the screw26 will be. either extended or reversed in direction of longitudinaltravel by reason of the directionof rotation. of the clutch member 29. V

The cross bar '21 carried by the two tubes 19 and 20.has twoslides 7 O,71 therein,'the

' position of which slides is determined by the rotation of the screw72. Said screw is operated by the hand wheel 73. The two slides 7 O, 71have end members 7 2", 7 2 and bottom'members 73, 73" secured thereto.When the machine is to be used, the box formed by the ends 72, 72" andby the bottom members 73,73 and top members 74, 74form an inclosure openat one end in which the-cushion stufiing material is first-assembled.The bottom of the box consists of the two' pieces 73,, 73" while the topof the box consists of the two pieces'74, 74 slidable one "over theother in pairs. They are each of such width as to permit substantiallythe whole of the beam 21 to be used when desired. The members 74, 74'are hinged at the corners 75, 76 to the end members 72, 72". 7

Since the material with which the cushion stuffing box is made iscomparatively thin, the beam 21 is provided with a rigid arm 46 whichsupports the bottom of the cushion stuflin box at its center, and with ahinged arm 41 which-holds the top of the cushion stuffing box down whenthe two members 74,74 are folded over uponthe top of-the material in thebox. The arm 47 is pivoted at-48- on the cross beam.21. The arm 47 has-aheel piece 49 which bears upon a block 5O carried-by a spring 51- tosecure the arm 47in theposition shown in Fig. -4. When in this position,the-.-block. 50 bears upon a lug:52carried by the cross beam. 21 andholds the arm 47 down. To release the arm 47, there is a handle 53 whichhas a portion 54 behind the spring 51, so that upon moving the lever 53to the left Fig; 4, the block 50 will be releasedfrom the heel piece 49and permit the arm 47 to be raised out of contact with the top members74, 74. The guide 24 has two lugs 55, 56 at the-sides thereof, whichguides support two rods 57, 58. Said rods extend through the crossbeam'21 and terminate in a pusher bar 59, said pusher bar being for thepurpose of pushing the filling within the stufiingbox in the cushion.

The slides 70, 71 are movable along the cross beam 21 and are heldinaafixed position with'res'pect thereto by means of the right and leftthreads on thescrew 7 2, said screw being operated by means of the handwheel 73. V

- Mounted upon the screw 26 are two 7 clamps 60, 61 which are held in afixed position on said screw by means of the two split clamps 60, 61 andthe tightening bolts 62, 63. These clamps-haveheel pieces 64,55 whichare adapted to contact withthe levers 36, 37 respectively to disengagethe clutches, as will be later explained.

The operation of the apparatus sis as follows: The workman opens thesmiling box by raising the arm 47 .and' by raising the top members74,174.. He then separates the sides of the box so that it issomew-hatwider than the cushion to be formed, and fills it with the hair,.cottonorother fiber or material with which the cushion is to be stuffed. Whenthe proper amount of fillhas been placed in the box, thetop pieces 74,74 are closed down upon the cushion filling, and'the arm 47 is thenpushed down upon-the top of said topmemhers 74, 74 to hold them down.The-screw 72 is then turned"tonarrow-the material within the stuffingbox enough to-Epermit the cushioncover to he slipped overthe :lJOX. Thecushion coveris then pushed over the box and *the lever 38 is thenoperated'to cause the belt 70 and member 31 to drive the member 29,whereupon the beam :21 will be turned toward the stand 1. This will becontinued until theguard 64:-contacts with the lever 36; whereupon theclutch member 31will-be released from" the member 29 and the machinewill-stop.

The result of this is that 5 the material within the stufiing box willbe pushed out of r the same by the pusher .bar 59,and into the cushioncover which-sis held against 1111611113- terialby the workman. As soonasthe machine stops, the made up cushion-will be removed from it and thelever 39 may be .operated totcause the box to slide out. over the pusherrod 39 in preparationforthe pro: duction of another cushion.

In order to provide for-.therapid operation of the machine, the stops60,.6l.and=-the pusher bar 59are adjustablein position so that theamount of movementof the box for means to increase or holding thestufling material is limited to the precise amount necessary for a givencushion.

Having thus described my invention, what I claim as new and deslre tosecure by Letters Patent of the United States is as follows, expressreservation being made of permissible modifications.

1. An upholstering machine comprising an open ended extensiblereceptacle having overlapped hinged top members and overlapping bottommembers, means to hold said receptacle closed, a pusher bar therein, andmeans to move the extensible receptacle so that the pusher bar thereinwill push material out of the receptacle and into a container placedover the receptacle;

2. An upholstering machine comprising a support, a pair of slidable armsthereon, an extensible receptacle having overlapping hinged top membersand overlapping bottom members, means to hold the receptacle closed,diminish the width of the receptacle, a pusher bar therein, and means toretract the receptacle to push materials therein, out of the same, andinto a container placed over the receptacle.

3. An upholstering machine comprising a base having a pair of slidablearms, a cross bar connected with said arms, an extensible receptaclecarried by said cross bar, means to increase or diminish the width ofthe receptacle, means to hold the receptacle closed, a fixed pusher barwithin the receptacle, and means to reciprocate the receptacle to pushmaterials therein, out of the same, and into a container placed over thereceptacle.

4. An upholstering machine comprising a fixed base, slidable armsthereon, a cross bar connecting the arms, an extensible receptaclecarried by the cross bar, means to increase or dimimsh the width of saidreceptacle, a fixed bar therein, means to move the receptacle in eitherdirection, and means to automatically stop the movement of thereceptacle at either end of its travel.

5. An upholstering machine comprising a fixed base, slidable armscarried thereby, a cross bar carried by said arms, an extensiblereceptacle carried by said cross bar, means to increase or diminish thewidth of said receptacle, means to hold the receptacle closed, a fixedpusher bar within the receptacle, a screw extendin from the cross bar, athreaded clutch mem er through which the screw extends, and means todrive said threaded clutch member in either direction, at will, to causethe movement of the receptacle.

6. An upholstering machine comprising a base, slidable arms carriedthereby, a cross bar connecting the arms, an extensible receptaclecarried by the cross bar, means to increase or diminish the width ofsaid receptacle, means to hold the receptacle closed, a fixed pusher barwithin the receptacle, means to retract the receptacle so that materialsthere- 'in will be pushed out of the same and into a container placedover the receptacle, and means to automatically stop the movement of theextensible receptacle.

In testimony whereof I have hereunto set my hand this 26th day of April,A. D. 919.
